and the section of freeway in Northern Michigan was named the most scenic new highway in the US in 1963 by Parade magazine. The first part of the Chrysler Freeway opened to traffic on June 26, 1964, the southern mile (1.6 km) of which was designated I-375. The segment of I-75 through the Downriver suburbs of Detroit between the US 24 (Telegraph Road) connector and M-39 (Southfield Highway) was completed on December 28, 1966. The same year, I-75 was scheduled to open southward from 11 Mile Road to M-102 (8 Mile Road). In 1967, two segments of freeway opened. One was from Kawkawlin to Standish in October, and the other through Detroit extended I-75 along the Fisher Freeway in December. The first section of M-76 freeway from Standish northwesterly to Alger was scheduled to open in July 1968. A section of the Chrysler Freeway through Detroit opened on December 19, 1968, and the remainder was scheduled to open on January 10, 1969. In 1970, I-75 through Detroit was completed, and two additional sections of M-76 were converted to freeway. The northern section ran from the US 27-to-I-75 transition south of Grayling to the Crawford–Roscommon county line, and the second was an extension from Alger to the West Branch area. The first ice-detection system in the state was installed on the River Rouge bridges in the Detroit area in an attempt to maximize driver safety. The next year, the last section of the Chrysler Freeway in Hazel Park was finished when an interchange for the then-unbuilt I-696 was completed. Another segment of the M-76 freeway was completed at the same time, bypassing Roscommon. The final section between Alger and Roscommon was opened on November 1, 1973, in a dedication by Governor William G. Milliken. Since the freeway was completed in 1973, a few changes have been made to I-75 in Michigan. From 1973 to 1975, I-75 was widened from four to six lanes from south of Flint to north of Bay City. MDOT truncated US 2 to end in St. Ignace by removing it from the I-75 freeway in 1983. In 1986, US 10 was truncated to Bay City, removing its concurrency with I-75 from there to Clarkston. Two years later, the original bascule Zilwaukee Bridge across the Saginaw River was replaced by a much higher structure slightly north of the former bridge. All of I-75 within Michigan was named the
